SLS RS-25 Engine Test, 29 November 2023 (gimbal test)

An Aerojet Rocketdyne RS-25 rocket engine (RS-25 developmental engine E0525) was tested on the Fred Haise Test Stand (formerly A-1 Test Stand) at the John C. Stennis Space Center in Mississippi, on 29 November 2023, at 19:32 UTC (13:32 CST). This was the third hot fire test out of the 12 planned in the final round of certification testing ahead of production of an updated set of engines for NASA’s Space Launch System (SLS) that will be used beginning with Artemis V.

The old guys that designed and tested those engines must be proud.

Top marks for designer of the pipes carrying the mega-below zero propellant between the tanks and rocket engine gimbal for not cracking with the degree of flexing.

Indeed, maybe the extreme cold is what makes it possible, probably some exotic alloy.
the hi pressure side is nearly 500 bar, enough to fill a balloon in a nano second.

Nice going

Great engine, a real monster - and now imagine the even much bigger F1 of Saturn 5 running almost 6 decades ago

[@AnalogDude_]

How big does the perimeter has to be free of people during such test?
Is the whole area fenced off? do they employ police or forest guards?

That’s the engine I want onto my rocket, thirteen please. No way a Raptor engine can suffer 104 % for nine minutes...
